SPECIFICATION forming part of Letters Patent No. 770,836, dated September 27, 1904.

Application filed August 15, 1901. Serial No. 72,198. (No model.)

To all whom it may concern:

Be it known that I, GEORGE WASHINGTON, of New Brighton, in the county of Richmond and State of New York, have invented certain new and useful Improvements in Lamps; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in lamps, and more particularly to a frame for incandescent lamps, an object of the invention being to provide improved means for removably securing the vaporizing-tube in place and permitting its removal without disturbing the other parts of the. lamp.

A further object is to provide an improved frame to independently and removably support the burner and vaporizer.

A further object is to provide improved airinlet tubes which will take the air from outside the lamp and below thepoint of burning to insure the supplying of pure oxygen to the burner.

A further object is to provide an improved lamp whose component parts can be readily and quickly assembled and any part thereof which may become broken or injured easily replaced by any one of average intelligence. With these objects in view the invention consists in certain novel features of construction and combinations and arrangements of parts, as will be more fully hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in elevation illustrating my improvement. Figs. 2 and 2 are views of the main portion of the lamp-frame. Fig. 3 is a View in vertical section with parts removed. Fig. 4: is an enlarged detail view in section of the vaporizing-tube and oil-supply'connection. Fig. 5 is a plan view of top of main frame. Figs.

6, 7, and 8 are views of modified forms of my invention.

1 represents a pipe provided at its upper end with a coupling 2 for its attachment to the gas-pipe or other support. The lower end of the pipe 1 is screwed into a casting 4, provided with ducts 5 for the reception of the ends of a circular pipe .5 around the vaporizing-tube and perforated on its inner side for burning the gas to start preliminary vaporization. The casting A is provided on opposite sides with notched ears 6 for the reception of the upper ends of long screws 7, having nuts screwed thereon to secure a horizontally-disposed ring 8, which, with the parts carried thereby, constitutes the main portion of the frame, said screws 7 also passing through lugs 9, projecting outward from a tubular extension 10 on a sleeve 11, and spacing-sleeves 12 are provided on the screws 7 between the lugs 9 and ring 8. The flanged upper edges 14: of semiconical shields 13 are perforated to receive the screws 7 to hinge the shields and hold their flanged upper ends 14L against the bottom of ring 8 by means of the spacingsleeves 12, the hinged ends of said flanges 14 being cut away to permit them to swing, the

free ends of the shields being brought together to entirely close the space between the ring 8 and sleeve 11 and prevent drafts up through the lamp.

The tubular extension 10 is internally threaded for the reception of an externally-threaded sleeve 15, having an angular head 16 at its outer end to receive a wrench for turning it, and the head 16 is internally beveled to countersink the head of a screw 17, which latter projects through the sleev 15 and is screwed into a sliding plug 18 rovided on its upper face with a lug 1 0 move in a slot in the extension 10 and prevent rotary movement of the plug. The plug 18 is provided in its outer end with a horizontal oil-duct 19, having a short connecting-duct 2O projecting up therefrom and with which the oil-pipe 21 communicates. The oil-pipe 21 is flexible and secured to the plug 18 in any desired manner and connects the duct 20 therein with a duct 22 in the casting 4, with which duct 22 an oilsupply pipe 23, inclosed in a pipe 1, communicates, and said pipe 23 projects up through the coupling 2 and is closed at its upper end and has an opening in its side alining with a threaded hole in the coupling 2 for the attachment of a supply-pipe connecting the same with a suitable oil-tank. However, the oil-supply pipe may be secured to the outside of pipe 1 if desired.

the tubes 29 to direct the flame for preliminary heating against the vaporizing-tube when a wick saturated with alcohol is used;

. municates. The plug 18 when forced into the opening in the block 25 not only serves to connect the oil supply with the vaporizingtube, but also serves to hold the tube in the sleeve 11 and permit its ready removal by simply loosening the sleeve 15 to draw the plug 18 out of the opening in the block, when the vaporizing-tube will drop down through the sleeve 11 without disturbing any part of the lamp. The block also contains the means for operating the ordinary needle-valve in the vaporizing-tube, and said operating means is provided with a shaft projecting through the side of the'block and having a cylindrical enlargement 26 on its outer end, which is made with a peripheral groove to receive a screw 27, screwed through a ring 28, disposed on the enlargement, and said screw is provided on its free end with a knob or button 29 to facilitate turning it and secure itto the enlargement 26. It will be seen that by providing this improved device the screw can be set at any angle, according to the position of the lamp, to most conveniently operate the needle.

The ring 8 is provided on its inner face, equidistant apart, with a series of pockets 27, into which the lower ends of the air-inlet tubes 29 are removably supported, and said This commingling-chamber and burner-tube 30 are of the ordinary construction and have provided on their lower ends the auxiliary burner 31, which may be made integral with either the burner-tube or the vaporizing-tube or may be made separate and removably secured in place. 7

A removable sleeve 32 is supported between but when gas is employed for preliminary heating there is no necessity for this sleeve 32, and it can be dispensed with.

An incandescent mantle of ordinary construction is supported on the main burnertube, and a small gas-jet 32 projects from pipe 1 to light the same. A chimney 33 is secured above the mantle, and to the tube 1, by means of a clamp 34, on'one side of said chimney, is provided at its upper end with a deflector 35 and at its lower'end with a small reflector 36. The tube 1 is bent to centrally dispose the chimney 33 and is provided near its upper end with an adjustable collar 37, on which a large chimney '38, having hoods 39 at its top, is supported, and a large reflector 40 is secured to the lower end of the chimney 38 to throw the light down onto the ground when the lamp is hung high; but when the lamlp is low this reflector 40 can be dispensed wit A globe 41, inclosing the burner, is held against the chimney 38 and is supported on a flanged ring 42, which latter is provided with internal lugs 43 to support the ring 42 and globe in place, as will now be explained. The ring 8 is provided beside each air-inlet opening with a vertical groove 44, communicating with said opening by a short groove 45,and the lugs 43 are pushed up in the vertical grooves 44 and the ring 42 turned to move the lugs 43 through the grooves 45 into the air-inlet openings in which they rest and are supported, and when it is desired to remove the globe it is simply necessary to lift the ring 42 and turn it slightly until the lugs 43 move into the vertical grooves 44, when the ring and globe can be slipped down and off. The ring 42 is made with holes to aline with the holes in the ring 8, so as not to interfere with the supply of air to the burner.

Instead of providing the construction of oil-pipe and vaporizer connection above described I might employ a joint connection, as

pending arm 49 on one side of ring 8 and mount in its lower end the oil-pipe coupling 50, which isadapted to be secured into and support the vaporizer, hence dispensingwith the sleeve 11 and all connecting parts between the same and ring 8. This arm may be made separate or cast with ring 8. This frame may, if desired, be used on a bracket-lamp by connecting the same at one side to the bracket by any well-known means.

I makeno claim in this application to the shade or globe support herein shown and described, but reserve the right to claim same in a separate and subsequent application.

Various slight changes might be resorted to in the general form and arrangement of the several parts described without departing from the spirit and scope of my invention, and hence I would have it understood that I do not wish to limit myself to the precise details set forth, but consider myself at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of my invention.
